More regex help

Hello,

I need a regex that will take a block of text and highlight HTML syntax.

Text will be one color, tags will have another and attribute values will have another.

I don't need to highlight the text, and these are the two lines I use to highlight now:

Code:

    $text = preg_replace("/&lt;(.*)&gt;/","<span style='color:#000099;font-family:monospace;background-color:#CCCCCC'>&lt;\\1&gt;</span>",$text);
    $text = preg_replace("/&lt;(.*)(&quot;|\')(.*)(&quot;|\')(.*)&gt;/","&lt;\\1<span style='color:#0000FF;font-family:monospace;background-color:#CCCCCC;'>\\2\\3\\4</span>\\5&gt;",$text);

However they're very buggy. It only highlights the last attribute value of each line, and it highlights all the text in between tags as if they were tags as well.

Any ideas to improve these?

Okay, I got the tag problem fixed. Now all I need to fix is the attribute value problem.

Well, it seems that with a bit more thinking, I got the problem solved.

This is the solution I ended up using:

Code:

    $text = str_replace("&lt;","<span style='color:#000099;font-family:monospace;background-color:#CCCCCC'>&lt;",$text);
    $text = str_replace("&gt;","&gt;</span>",$text);
    $text = str_replace("=&quot;","=<span style='color:#0000FF;font-family:monospace;background-color:#CCCCCC'>&quot;",$text);
    $text = str_replace(" &quot;"," <span style='color:#0000FF;font-family:monospace;background-color:#CCCCCC'>&quot;",$text);
    $text = str_replace("&quot; ","&quot;</span> ",$text);
    $text = str_replace("&quot;&gt;","&quot;</span>&gt;",$text);
    $text = str_replace("&quot;/","&quot;</span>/",$text);

Thanks anyway,

It's amazing what you can accomplish with a little bit of thought. And 2 Litres of coffee. And 10 packs of cigarettes. And 72 hours without sleep...
